Clicking on our banner tries to take me to http://karinth.com:2345 instead of to a telnet connection. As a result, it tries to download a file but does not take me anywhere. We chose the telnet connection on banner clicks.

Hmm. It looks like the banners are still picking the wrong target even though it's been specified. Your banner is currently marked to direct to the website, but is using the address you specified for the telnet connection. Let me dig around in the code and see what blew up.
